Is drinking only water good for you while pregnant ? It sounds like a silly question but 1  year and a half after I had my first child in 2013 I lost weight and stop drinking juice and soda. June 27 would have made 2 years since I lost my weight but I'm pregnant. Not only the fear of gaining so much weight like I did my first pregnancy but not being able to lose it is what scaring me. I'm 5wks & 6dys and my stomach was flat but now it's fulling up as if I'm gaining weight or pregnant  but I've been the same weight scale hasn't moved. But I was wondering I know you need vitamins fruits and veggies I know some juices give you that but I'm not up for going back to drinking any kind of juice (apple , orange etc) will it be safe to drink in only water and seltzer water while pregnant ?
